The MongoDB object type is not stored

Let me share my customized user schema below.

var userSchema=mongoose.Schema({
    //name:{type:String},
    username: {type:String, required:true, unique:true},
    password: {type:String, required:true},
    habit: {type:Object, required:true}
});

However, I encountered an issue where the habit field is not being saved when a new user (newbie) is added to MongoDB.

var newbie=new User({
    username:username,
    password:password,
    habit:{}
});
console.log(newbie);

Upon checking console.log(newbie), the result shows "{ _id: ~~~????, username: 'babo', password: '1234' }" without the habit field. How can I properly include the habit attribute?

Answer №1

By default, MongoDB does not store empty objects. To save an empty object, you need to provide a second parameter { minimize: false } when defining your Schema.

Try using the following code snippet to resolve this issue:

var userSchema = mongoose.Schema({
    //name:{type:String},
    username: {type:String, required:true, unique:true},
    password: {type:String, required:true},
    habit: {type:Object, required:true}
}, { minimize: false });
